I've gotten U-boot installed into the SPI by using the
So in theory I can boot from not just eMMC or SD but also USB, TFTP, etc.
Also, in theory, can boot things that don't have to proper U-boot bits for
This works for things like Armbian and such that have Rock64 compatible
images that already booted without u-boot in SPI, but does not appear to
work for Fedora.

Any ideas what I can try? The armhfp I'm guessing fails because of a lack
of support for the device, the dtb file doesn't exist. But the AArch64
image has a more vague "FDT_ERR_BADMAGIC" ...

If it's a self built ATF you can do as you like as long as it's got
the bits of u-boot needed to boot UEFI. For us to ship it in Fedora we
need to build it due to policies.

That's my understanding, we can tweak the locations too, it's just the
SPL that needs to be in a specific spot.

The Pine64 works fine if it's a MBR partition, we've supported that
device for a couple of releases.

Shouldn't make any difference what so ever, upstream u-boot will boot
either as per the UEFI standard.

The FAT16 partition is where all the EFI bits reside, they are core
for booting an aarch64 Fedora system.
